IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 155,527, dated September 29, 1874 application filed September 4, 1874.

To all whom it may concern:

Be it known that LTHOMAS LANGSTON, ot' Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Lanterns; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent in- Figure '1 a side view; Fig. 2, a top view with the yoke turned away; and in Fig. 3 a transverse section.

This invention relates to an improvement in that class of lanterns in which the top globe and base are held together by a yoke pivoted to the base, and extending up over the top so as to be turned away for the purpose of separating the parts, and removal of the globe.

The usual method of securing the yoke in its position to hold the parts, has been to apply a screw or spring to bear upon the top at the center, but this is an uncertain orinsecure arrangement.

moval of the yoke until the cap is returned to bring the said groove into the path through which the yoke will move.

A is the base to which upon opposite sides,

as at a, the yoke B is hung, and which extends up over the globe O and cap D, in substantially the usual manner, the cap D setting onto a bead on the globe, and the globe in the base, as in the usual construction. At the center'of. the yoke, upon the under side, a headed or flanged stud, d, is set, and in the top of the cap, which is raised, as at E, for the purpose, a radial groove or slot, f, is formed, so that as the yoke is passed up over the parts, as in Fig. 1, the studd will pass into the slot f,- then by turning cap to bring the slot out of the line of the path of the stud d, as denoted in broken lines, Fig. 2, the yoke cannot be turned from its holding position. a

Inorder to draw the parts closely together the surface around the slot f is inclined upward, so that the yoke in passing onto the cap will force the cap down according to that incline.

To remove the globe, return the cap to bring the slot into the path of the stud; then turn the yoke away, as shown by broken lines,

Fig. 1.

I claim as my invention- 1 The cap D of a lantern constructed with the radial slot E, combined with the yoke B, provided with the stud d, constructed and arranged to operate substantially as described.

THOMAS LANGSTON.
